[Buildroot] Built mipsel cross-compiler error on buildroot

[Doug Brewer]

Hello,

I tried to use buildroot snpashots(20061128) to build mipsel cross-compiler,
I got the following errors;

Would you tell me how to fix? Thank you very much.

This looks like an inconsistency in the kernel headers.
asm/sigcontext.h is present, but asm/sgidefs.h is not (at least where
it's expected to be).

Make sure you have unifdef installed.  Try varying the version of the
kernel headers (e.g if it's 2.4.x, try 2.6.x and vice versa).  If it
doesn't help, try the released version of uClibc.  Also try another
compiler version (I would start with gcc 4.1.1).

First off, thanks for your reply. I have unifdef installed and tried
gcc 4.1.1 with no luck.
As you pointed out, asm/sgidefs.h is missing. I copied this file into
buildroot/toolchain_build_mipsel/linux/include/asm and
buildroot/toolchain_build_mipsel/uClibc_dev/usr/include/asm, the
problem will be solved.
I use linux-2.6.18.3 kernel headers, I think buildroot developers
might provide a patch to
fix that problem, thanks.
